To aZZ whom/it may concern: 7

Be it known that I, GEORGE E. Daanow,

citizen of the United States, residing at 77 t Willamette street, Eugene, in the county of Lane and State of Gregon, have invented certain new and useful Improvements in Processes of Removing Stains from Fabrics. of which the following is a specification.

' This invention relates to nev and useful cleaning compounds for use particularly in processes for removing stains of all kinds from fabrics, more especially white goods of vegetable fabric, such as cotton. linern. straw and paper and the primary object is to rovide solutions which when applied,

, wil not injure the fabric and which will render the process more expeditious and cheaper.

In carrying out the process, .1 use two .eparate and distinct solutions which for convenience will be termed solution A. and

- prises reaction product of three essential ingredients, any one of which, if merely applied to a stain or coloring matter, would he Specification of Letters Patent.

ineffective, although if permitted to remain for some length of time would destroy the color and in most instances alsodestroy the goods. However. by first applying solution A to the stain and then applying solution B, thereto a product is formed. the same being a gaseous combination of chlo'rin and oxy gen. 'Ijhis gas instantly disintegrates the coloring matter, leaving the goods white and absolutely free from injury.

I am aware that the three inain ingredients of my compound have been 'used individually heretofore for cleaning purposes, but my invention consists in the particular combination-of the three main compounds which generate a new and activestain-removing product.

It has been stated above that this compound is particularly adaptel for use on vegetable fabrics but the same may also be used as well for the removal of stains from certain classes of wool and silk. In such uses, however, the solutions must be applied with considerable judgment. /Vhat I claim is:

. The process of removing stains from fabrics consisting in subjecting the stained fabric to a solution of oxalic and sulfurous acids and then applying a solution of calcium hypochlorite thereto.

" In testimony whereof I aiiix my signature in presence of two witnesses.
